I've resolved this issue (for now by configuring flutter to use Java 17).

It looks like Android Studio update installed Java 21 and by running: flutter create .
I could see...

The configured version of Java detected may conflict with the Gradle version in your new Flutter app.

[RECOMMENDED] If so, to keep the default Gradle version 8.3, make
sure to download a compatible Java version
(Java 17 <= compatible Java version < Java 21).
You may configure this compatible Java version by running:
`flutter config --jdk-dir=<JDK_DIRECTORY>`
Note that this is a global configuration for Flutter.


Alternatively, to continue using your configured Java version, update the Gradle
version specified in the following file to a compatible Gradle version (compatible Gradle version range: 8.4 - 8.7):
/Users/hamishnorton/factory/flutter3244/android/gradle/wrapper/gradle-wrapper.properties

You may also update the Gradle version used by running
`./gradlew wrapper --gradle-version=<COMPATIBLE_GRADLE_VERSION>`.

See
https://docs.gradle.org/current/userguide/compatibility.html#java for details
on compatible Java/Gradle versions, and see
https://docs.gradle.org/current/userguide/gradle_wrapper.html#sec:upgrading_wrapper
for more details on using the Gradle Wrapper command to update the Gradle version
used.

I installed Java 17 from
https://adoptium.net/temurin/releases/?os=mac&arch=any&version=17

Check it installed with:
/usr/libexec/java_home -V

And set the flutter JDK directory with:
flutter config --jdk-dir=/Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home

Upon running flutter doctor -v it shows Java 17.
And on running flutter create --platform=android . the message has gone.
And I can now launch the app.

What I am unsure about is that...

Comes with Java 21 and this causes an issue for the mixpanel_flutter package.
I've avoided the problem be pointing my flutter installation to Java 17 for now.
